Let’s take a look at the benefits and challenges of integrating third-party APIs into custom app development services.

Enhanced Functionality

Third-party APIs are used to integrate many software components including chat, access/authorization, payment gateways and geolocation platforms. Integrating these APIs enhances the functionality of your app. For example, chat integrations such as WhatsApp and Zendesk chat allow live chatting options within an app. Similarly, payment gateways such as PayPal and Stripe allow seamless transactions as compared to developing a brand new internal API which would be costly and resource-intensive. There are certain benefits and challenges which are as follows:


Third-party APIs empower the apps to enhance the custom application’s functionality without starting from scratch. The APIs empower developers to add rich features to their applications without having to invest their time and effort into developing the feature by writing code and exhausting time. Adding payment gateways, social media integration and geolocation services, APIs offer a treasure of features. Similarly, leveraging the already available APIs reduces the development time and cost. Developers in this case focus on the app’s core functionalities integrating robust APIs for supplementary features.


Although it brings heaps of benefits, integrating third-party API has a major challenge of dependency associated with it. Depending on external APIs relies on the stability and longevity of the external third-party services. In case the API is discontinued or overhauled completely, the functionality of integrated features might get disrupted. This will eventually impact the user face if they are uncertain of the user experience and might not use the mobile app in future. Hence, deciding on what APIs to use is a critical decision.

Enhanced User Experience

Integrating APIs provides a seamless and enhanced user experience. With various digital platforms and applications on the cards, the user experience is fortified using the APIs. Access to real-time updates, rich content and services from external applications, faster loading times, personalization, and efficient collaboration, enriches the user experience. With digital ecosystems evolving, the strategic use of APIs contributes to the creation of dynamic, feature-rich and user-centric applications.


With familiar and user-friendly functionalities offered by third-party APIs, the user experience delivered is seamless. When using different apps, the customers don’t have to make themselves with new technology every now and then. Since third-party APIs are consistent across all applications and devices, the users are familiar resulting in an enjoyable and familiar experience. Secondly, a great benefit is that of scalability. Since the API is not internal, scaling the app will also lead to scalability in APIs as well. This will add new features and manage the increased user load with efficiency.


Security and safety are the primary concerns when creating and developing custom mobile applications. Customers want full privacy and data security to trust the application. Third-party APIs might collect user data, which might compromise the privacy and safety of users. Developers are required to assess the custom app for vulnerabilities and loopholes. Ensuring data safety will definitely boost the brand image and more customers will be attracted to it.

Real-Time Data and Updates

Real-time data access enables custom mobile apps to access up-to-date information from all available external sources without any delay. With updates included, third-party APIs are aligned to integrate real-time data so by deploying third-party APIs, your app can gain real-time data access. For applications such as stock market information, products or services websites, third-party APIs enable timely retrieval of information to make rational decisions. The information is hence accurate and efficient for a decision to be made.


As discussed above, the primary benefit of third-party APIs is the access to fresh data. This ensures that the data is up-to-date. Dynamic applications that require real-time data including news websites, weather updates and financial data are dependent upon it. Location tracking, social media feeds, live streaming, and live scorecard/sports data are also part of real-time data access. For seamless functionality, real-time data is crucial. Moreover, third-party APIs are in automatic synchronization with external databases and servers eliminating the need to manually update the app. The app’s maintenance streamlines with automated updates.


Since the real-time data is linked with the third-party API servers, reliability can be a major issue. With downtime and delays faced in the external API, the app’s functionality might be affected and real-time updates can get delayed. This can create obstacles in user experience and hence, hinder the satisfaction and loyalty levels of customers.

Cross-Platform Compatibility

Third-party APIs, or APIs in general, are language-agnostic; they do not promote any specific language. This implies that APIs are coded for cross-platform compatibility, whereas software or applications are coded in specific languages. Though it is true, implementing API involves writing code to handle requests and responses in specific languages. A set of standards and conventions is employed to design APIs, facilitating communication between different software and components. This enables cross-platform compatibility across all devices so whether you are on iOS, Android or Windows, the experience is consistent.


Third-party APIs support multiple platforms and offer solutions that are viable across all operating systems and devices. There are native apps and cross-platform apps that focus on different functionalities and features, targeting different audiences. However, third-party APIs are beneficial for both. Particularly, this is advantageous for applications that want to target a broad audience on different platforms and operating systems. Easy maintenance and updates are also easy because of language-agnostic development. Developers can make updates without any problems rolling out security patches and bug fixes in an instance.


Although cross-platform compatibility brings a lot of advantages, the platform changes can be a challenge in third-party API implementation. Changes in the operating system or drastic updates can hinder the functionality of the app. The developers must stay one step ahead of platform updates to maintain ongoing support for the application. Testing complexity and security concerns are also major challenges in the cross-platform compatibility of third-party APIs.

Security and Safety

Security and safety in mobile app development in general are important considerations. Consumers are concerned about their data, particularly with financial, e-commerce and social media applications.
